JOSHUA HEUYARD, OF TEE-RE HILL, PENNSYLVANIA.

REPAIRING AND STRETCHING LAST.

Application filed June 13, 1910.

T 0 all whom it may concern:

Be it known that I, JOSHUA I-IEUYARD, a citizen of the United States,residing at Terre Hill, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements inItepairing and Stretching Lasts, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a boot last and stretcher, of that class whichis intended for repair work as well as for stretching the shoes.

The objects of the invention are to provide a stretcher and last of thiskind that is so constructed and operated that the shoe is stretchedevenly from the toe to the heelas the two halves of the last are forcedapart in a parallel manner to each other.

Another object of the invention is to provide a last and stretcher ofthis class that will be cheap, durable, effective, and contain fewparts.

With these and other objects in view, my invention consists in certainconstruction and combination of parts as will hereinafter be fullydescribed and claimed and illustrated in the accompanying drawings,which form a part of this application, and in which like figures ofreference refer to corresponding parts in all of the views; but it isfully understood that while I have here described my invention as shown,that I do not confine myself to the exact design as shown, as slightchanges may be made in the construction and arrangement of the severalparts without departing from the spirit of the invention.

In the drawings :Figure 1, is a top plan view of my improved combinedlast and stretcher. Fig. 2, is a longitudinal horizontal sectional view.Fig. 3, is a sectional view of the last, showing the same open, and theheel block with the gear case cap removed. Fig. 4, is a longitudinalvertical sectional view, showing the working parts.

Referring to the drawings, the last is formed of two halves 1, and 2,which are held together in a flexible manner by the wires 3, which haveone of their ends secured to one-half of the last, and the other endsecured to the other half of said last, and normally retain said halvesin contact Specification of Letters Patent.

with each other. Each of the halves or movable members 1, and 2, has theinner or abutting face provided with a longitudinal-- extending groove4:, which extends from the rear end of and terminates at a point removedfrom the forward end of the members. The groove 1, near the center, isformed with an enlarged portion 5, which has the tapered or beveled ends6, and 7.

Mounted in the groove 4:, and enlargement 5, is a sliding member 8,which is formed with the wedge-shaped forward end 9, and the tubularrear end portion 10, which is screw-threaded to engage the forward endof the shaft 11.

Within the heel block 12, is mounted a gear case 13, within which iscontained the bevel gears 1 1, and 15. The gear 15, being secured uponthe rear end of the shaft 11, which extends through the hole 16, in saidheel block 12. The bevel gear 14;, be ing adapted to rotate the gear 15,and shaft 11, by the action of a detachable wrench or key 17 which isprovided with a squared end 18, for engaging a squared hole 19, in. thetop of said gear 14:. Said gear case 13, being retained within said heelblock 12, by the plate 20, and screws 21, and also by the threadedcollar 22, which is secured upon the end of the shaft 11.

The device, in a closed position, having been inserted into the shoe,and the key then operated to revolve the gears, the last is first movedaway from the heel until the toe of the last has reached the toe of theshoe, when the last and heel cannot be farther separated, but as themember 8, is still advanced by the shaft 11, its forward wedge-shapedend 9, engages and slides upon the beveled grooves of the last, thusforcing the halves of the last apart from each other, and as the twohalves of said last are flexibly joined together they will exert an evenstretch upon the shoe.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is The herein described repairing andstretching last comprising a heel section, a last section formed of twohalves having registering recesses therein, a spreader mounted withinthe said recesses, means upon the heel section for reciprocating thespreader within the recesses, and a wire binder extending longitudinallybetween the In testimony whereof I afiix my signahalves of the lastsection, one end of the ture in presence of two witnesses.

Wire binder being secured to one of the JOSHUA HEUYARD halves toward thefront of the last section,

while the opposite end of the wire binder Witnesses: is secured to theother half of the last sec- WM. J. COULTER, tion toward the rear endthereof. MABEL L. LEFEVRE.
